Putting the nail in the myth: 24/0 vs 18/6

**GrowingMadness** · 05-18-2009, 02:07 AM

I can't find my old 7 page thread regarding this.

There we've had a lot of debates whether continuous light is better than 18/6

We did agree that plants don't need the dark time to GROW

But when they have the dark time they STRETCH

So what I did was make an experiment. One plant was under 24/0, the other under 18/6 for several days.

Result?

18/6 is 2x bigger

Why?

It stretches during the dark time, allowing more room for leaves to grow and more light for each leaf.

There, now it all makes sense. If you want your plants to grow faster, put them on 18/6.

i agree with this my mate is doing constant 24/0 lights and im doing 18/6 and my plants look to be a little bigger and more green on the leaves his are are more see though yellowish type you know what i mean ?

18/6 is the ticket. Saves on power and the plants like it.

Check my grow. 2 weeks left

all this really proves is that if you do 24/0 verse 18/6 you can have more compact plants...sounds great if you have space constraints....I believe the real debate on 24 verse 18/6 is male to female ratios NO?

Well, are the plants clones from the same mother? If not, the test results is rather biased/compromised.

Twice as big. What does that mean? Twice the height, but same amount of vegetation? Twice the vegetation?

BBB is right. I think you have oversimplified this just going by plant height. There are MANY other things to consider. For example- A short compact plant will shade its own lower nodes, whereas a taller somewhat stretched plant will allow more light though to the lower foliage. This will definitly affect eventuall yeild. And that is what we are all MOST interested in. YEILD. Not just height.
For the record and with ALL things considered, I do believe 18/6 to be the way to go.

I have to say that this thread proves NOTHING.

If you are going to do an experiment like this and have people take you seriously then you need to be a hell of a lot more organized. You are just expecting us to take your word on it.

You need to have 2 IDENTICAL grow rooms. Same light, same temps, same mediums, etc., etc., etc. Grow at least 2 plants of the same strain per room and publish a very detailed journal with pictures.

Right now it's just hear say.

As I've said before, Call Mythbusters!

its funny you mention that because i am trying to figure out a way to do this, along with some other experiments, on my next grow... i just have to figure out how to rearrange... if i can figure it out it will by like a mythbusters - "weed episode special"... a few different pruning techinuqes for growth and yield comparison under 2 different light scedules... plus some germinating, rooting, and cloning things...
